Outline

Where we are2010 prototype of E911 services

How we got here Implementation of mobile telecommunications standards Implementation of localization and geospatial standards

Where we are goingExtend E911 scenario and prototype indoors Implement other localization and geospatial standards required

to accomplish this

Standards Used to Improve Situational Awareness in E911 Prototype 3GPP IMS to

provide a SIP/IP core network infrastructure

route 911 calls OMA LOCSIP to

convey terminal locations OMA Presence SIMPLE to

publish status and notifications OMA SUPL to

perform network-based position determination of terminals

perform device-based position determination of terminals

IETF LoST to select the PSAP to answer 911 calls

GSMA RCS to publish locations and presence perform user-based position

determination of terminals IETF HELD to

perform network-based position determination of terminals

WiMAX to transmit and receive voice, video,

and other situational data 3G-GSM Networks to

transmit/receive situational data perform network-based position

determination of terminals

Let’s Take E911 Indoors

Our technology demos have considered only outdoors emergency scenarios

We now plan to extend the testbed by moving the emergency scenario indoors

IETF PIDF-LO, OMA SUPL are existing standards that are being extended to support indoor locations and context.

Even richer context could be provided by OGC CityGML.

Seamless Outdoors/Indoors Contextualization

8

New Context and Requirements

Extensions to scenario Fire within Chemistry Building Need to provide indoor navigation support to

emergency responders New Requirements

Indoor localization network- Seamless transition between world and local coordinate

systems- Accurate real-time positioning

Building Information Model (BIM) catalog services- Feature-rich model of building interior- Content and access-descriptive metadata for BIM- Catalog service to help find BIM for a location

BIM data services (WFS)- Application to extract and return floorplan(s)

BIM LBS (WMS)- Contextualize indoor location with floorplan- Compute current location and routing information

More Standards

Indoor E911 Enablers – Other Standards

IETF PIDF-LO Provide Indoors Civic/Geodetic coding Provide Relative Location Georeference World CRS – Local CRS

GSMA RCS Publish indoor/outdoor locations and presence Perform user-based position determination of terminals, indoors and

outdoors

OMA Presence SIMPLE Improve situational awareness through status publish and

notifications based on indoor extensions to PIDF-LO

OMA LOCSIP Convey indoor and outdoor terminal locations Make outdoors/indoors transition more seamless

Proposed Geospatial Enhancements to E911 Prototype 1. 911 call made by CALLER

2. Select the PSAP to answer the call3. PSAP makes request to Location

Service for CALLER location4. PIDF-LO object for CALLER location

returned to PSAP5. PSAP client queries OGC CS for

geospatial data objects whose envelopes contain PIDF-LO location

6. OGC CS returns list of geospatial data objects that contain CALLER‘s location, e.g., maps, images, documents and CityGML building models, along with URIs/URLs for each.

7. PSAP application selects data objects of interest, e.g., a CityGML building model, and requests a floorplan map from an OGC WMS.

8. OGC WMS requests floorplan features from the OGC WFS that manages them.

9. OGC WFS returns floorplan features to the OGC WMS.

10.OGC WMS builds floorplan map from features and returns it to the PSAP client.

11.PSAP client application (or another’s application service) computes and displays navigation route to CALLER using responder’s current location and floorplan.

Significance of E911 Prototyping Activities to Geospatial Community

Demonstrate the value that standards offer to network communications for managing emergencies

Provide feedback to standards forums based on experiences from our demonstrations

Expose opportunities to enhance and integrate standards in ways critical for meeting the needs of decision-makers and emergency response teams
